Entomological impact of three years of clothianidin-based indoor residual spraying in two high malaria endemic districts in Cote d'Ivoire.

ABSTRACT:

Background

Indoor residual spraying (IRS) represents a major malaria vector control strategy to reduce malaria burden. The first major IRS campaign for malaria control in Côte d'Ivoire was implemented by the US Presidents Malaria Initiative in two malaria endemic districts between 2020 and 2022. This study report on the effect of clothianidin-based IRS on key entomological indices of malaria transmission in the IRS districts following three rounds of IRS with clothianidin-based insecticide formulations.

Methods

Pre- and post-IRS adult mosquito collections were conducted monthly in two IRS districts (Sakassou and Nassian) and two control districts (Beoumi and Dabakala) using human landing catches (HLCs) and pyrethrum spray catches (PSC) from April 2019 through December 2022.
